The Surface Transportation Board (STB) of the United States is a bipartisan, decisionally-independent adjudicatory body organizationally housed within the U.S. Department of Transportation. The STB was established in 1996 to assume some of the regulatory functions that had been administered by the Interstate Commerce Commission when the ICC was abolished. Other ICC regulatory functions were either eliminated or transferred to the Federal Motor Carrier Safety Administration or to the Bureau of Transportation Statistics within DOT. - Source: Wikipedia
